2014 Mercedes B-Class ED battery much bigger than previously stated

There was something unexpected hiding in the new configurator for the 2014 Mercedes-Benz B-Class Electric Drive: a $600 "Temporary range extender." Since we've never heard of such a thing, we had to click through for more. The official explanation runs like this: A suite of options to further increase your driving range includes added insulation of the doors and roof for to increase climate-control efficiency, along with an electrically heated windshield and a range-extending charge function. By pressing a button on the console prior to charging, the maximum charge level for battery will increased for the next charge cycle. The higher-capacity charge can provide up to 17 additional miles of range. The passive features that increase range should be standard in all models, we think. But we were more curious about the battery charge situation. How do you increase a maximum? And is it a good idea to do so? The configurator includes this disclaimer, after all: Range extender should only be used on a limited basis, and could shorten battery life if used excessively. How much is excessive? We investigate below. The B-Class ED has, according to the specs, a 28-kWh battery. First, let's understand what this "temporary range extender" is all about. The B-Class ED has, according to the specs, a 28-kWh battery. But Terry Wei, from the Mercedes-Benz USA product and technology communications department, confirmed to AutoblogGreen that the B-Class ED is actually hiding a 36-kWh battery, but the automaker is calling it a 28-kWh battery because that's how much energy capacity is used in day-to-day use. Most automakers publicly claim the actual capacity and then admit they use a percentage of it. The Chevy Volt, for example, has a 16.5-kWh battery pack, but a "full charge" only fills up around 65 percent of that. In the B-Class ED, the 28 kWh of useable energy provides an EPA-certified 87 miles of range. But, since there are eight kWh of reserve, the temporary range extender (we think of it as a software update accessed by a button) can access some of that and offer the aforementioned 17 miles. Now that we know what we're dealing with, this reminds us of an evolved version of the "remote wireless charging" feature that was touted in the Reva EV. Wei said that the reason the feature is optional is because Mercedes doesn't think most people will need it. Eighty-seven miles is plenty for your average EV driver, but when you want to have 100+ in the tank, you can.

Continental Automotive recalls 5 million airbag control units

Takata isn't the only supplier having airbag problems. Rival manufacturer Continental Automotive Systems announced a recall of 5 million airbag control units fitted to vehicles from Honda, Fiat Chrysler Automotive, Mercedes-Benz, and even a certain Chrysler-based Volkswagen. This sweeping recall has actually been in progress for some time, although the exact scope is only now becoming evident. In October of 2015, Mercedes-Benz recalled 2008 and 2009 model year C- and GLK-Class vehicles because their Continental-made airbag control units could corrode. Such a condition could cause the airbags to deploy without cause or warning, or in the event of a crash, not deploy at all. You can read all about it in our post from last year. Now, Continental's recall is going wide. Alongside the already recalled C and GLK, you've already heard about the 2008 and 2009 Honda Accord airbag recall, which we reported on yesterday. Now, Fiat Chrysler is announcing the recall of the 2009 Dodge Journey, as well as the 2008 and 2009 Dodge Grand Caravan, Chrysler Town and Country, and their rebadged counterpart, the Volkswagen Routan. Yes, one manufacturer is recalling another manufacturer's vehicle. The models listed above only amount to about 580,000 vehicles out of 5 million bad airbag control units. And since Continental will notify manufacturers who will then issue their own recalls, it's extremely likely that more brands and vehicles will be ensnared. Stay tuned.

Autoblog drives to the Arctic Circle

In Which Mercedes' Sprinter Becomes A Long-Distance Sherpa
In the wintery wilds of northern Alaska, even the cute little critters want to kill you.
As I am about to nod off on my long leg flight from Minneapolis to Anchorage ahead of driving to the Arctic Circle, the friendly twenty-something Alaskan knitting furiously in the seat next to me pauses and says, "When you're driving up there, don't open your windows." In the dead of winter? I hadn't planned on cruising alfresco, but her warning to keep the glazing snugged against the weatherstripping is one I would take to heart. She continues: "If you leave 'em open, a fox is liable to jump right in. There are lots of rabid foxes up there, and they leap into your car and just Go. To. Town." And here I was, thinking that a curious bear or maybe an ill-placed moose in the road was going to be my biggest potential four-legged threat. In the wintery wilds of northern Alaska, even the cute little critters want to kill you.
